Our son was driving on 287 south in new jersey around on 7-21-2019. it was a hot day. he had been driving home from the adirondack mountains for about 3 hours and 15 minutes. his speed was just under 70 mph in the middle lane when suddenly the car wouldn't maintain its speed. the car slowed down and would not accelerate, even though the engine made a sound like it was trying to accelerate. the red throttle warning light appeared on the dashboard. he pulled over safely and stopped and turned the car off. he waited about 10 minutes to start it again... when he turned the engine back on the red light was off and he drove home slowly in the right lane without incident. the next day we took it to the jeep service department. they tried the vehicle several times and could not identify the problem, and we took it home. we are scared, however, to drive it on the highway now!
While driving at highway speeds the traction control system, anti-skid braking system, and or the combined operation of these systems for stability control, engaged intermittently and unevenly causing the vehicle to pull to one side or the other. this has occurred approximately five times under three different drivers all at normal highway speed and under dry road conditions. when this happened, there was an audible noise (like a vibration sound) of the brakes being automatically applied and a pulsing in the brake pull. the system has engaged itself while the gas pedal was being applied at highway speed on dry pavement. immediately upon the system's application i moved my gas pedal foot to the brake where as i applied the brakes i could feel the pulsing in the pedal. this situation is an extreme safety hazard. when it occurs it both startles the driver and causes the vehicle to swerve to one side or the other. the system is definitely applying uneven braking to the wheels to cause the swerving. we have disengaged the traction control system in order to drive the jeep in a safe manner. however, it requires the driver to disengage every time you start the vehicle. at present each dealer has been nonresponsive in taking action to correct this vehicle problem, the vehicle is still under warranty. each time they say that their diagnostic system is not indicating any problems.
Whenever i hit a bump (ranging from small pot hole to larger pot hole) on the highway going 60+ mph, my cruise control will shut off by itself. speed decelerates very quickly and i have to get it up to speed quickly to avoid getting rear ended. this has been happening for just over a year and it happens every time i hit any kind of small bump at an accelerated speed. started happening around 5000 miles on jeep and still does it at 17000 miles.
While driving under normal conditions, i'll hear a single audible 'ding' and then see the airbag and esp light illuminate on dash along with the speed odometer drop from the speed traveling to 0 before normal operation. this happens much more often when the cruise control in engaged. it happened 5/14/2017 while traveling interstate 65 to such an extent that not only did i have to cancel cruise control, i actually had to turn if off to stop the dinging and flashing of the airbag and esp light. i had to finish the last 2.5 hours of interstate travel without cruise control.
